Aphid problems in greenhouse
The past two seasons I have been dealing with horrible aphid and thrips in my commercial greenhouses. We are around 6000 sqft and located in Northern MI. We are a retail greenhouse focusing on annual flowers and vegetables for spring sales. Our season is finished mid June most years. The past two seasons I have tried using lady bugs, aphid predators and other natural treatments, but this season, I cannot afford another infestation. What are the best products and applications for these pests?
